Satisfied for the most part. - I bought this for me, my daughter, and my husband. Unfortunately, they do not work. Both remotes and key finders flash after we put in the batteries but do not alarm. Very disappointed. Update: my daughter kept fiddling with it and she figured out that the battery must be installed underneath some hooks and then they worked. They have varying degrees of loudness. For us, E and H were the loudest and my husband got those because he tends to lose stuff every day. The double-sided tape does not really adhere very well. We were hoping to attach it to our phones but were unsuccessful. They were very useful to attach to our keys though. Review: Should have bought sooner! - Bought for my daughter a year ago and still working so i got myself a set with two receivers as the only complaint she has is loosing the only receiver she has. They work well - well worth the money. I have had a couple different ones that use your phone as receiver and had issues with both. This is simple/easy and just works. If tiles could be thinner that would be nice but they are reasonable size and not really an issue for me but only improvement that could be made. Covers my 2000sq ft house without issue. ## Features - 2020 New Version: Easier to be heard. Beep emitts from the side. Easier and louder to be heard when it's covered. Also the transmitter with lanyard can stand alone instead of using a separate base, more and more convenient to carry and use at home or outside - Used as two sets of key finder: Any of the transmitter can lead you successfully to the lost items. Use each transmitter with a random letter combination receivers in two different places, which makes it more convenient to use at home or in office, car or elsewhere - 8 Color-Coded Receivers: Hook the receiver to any of the 8 items and just click on the color-coded button to find them. Easy to use and operate. NO APP needed. Best π†πˆπ…π“π’ for π’π„ππˆπŽπ‘π’ and π…πŽπ‘π†π„π“π…π”π‹ People.

I got two remotes so I could keep one in the house and he could keep one in the car. They work great for the keys. I also wanted to put them on his wallet and glasses, but they are too large for either, so that was a disappointment and I'm still looking for a solution for those. However, I am going to put them on my dogs, who are getting old and little senile, and sometimes have a hard time finding their way back to the back door. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/178637029-2-rf-transmitter-and-8-receivers](https://www.desertcart.pl/products/178637029-2-rf-transmitter-and-8-receivers) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-04-23*
